Thermal Management: The Engineer’s Guide to Die Cast Heatsink Design

Die cast ADC12 has lower thermal conductivity than extruded aluminum. Here is how to overcome that physics limitation through optimized fin geometry, flatness control, and surface emissivity to build high-performance heatsinks. In the world of power electronics—whether it’s a 5G base station, an EV inverter, or a high-bay LED fixture—Heat is the enemy of reliability. […]
